1909. Serial N 0. 519,530.

To all whom it may concern:

Be it known that I, HARRY R. CANFIELD, a citizen of the United States, and residing at New York, in the county of New York and State of New York, have invented certain new'and useful Improvements in Coin Operated Vending-Machines, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to what are known as coin operated vending machines; and the object thereof is to provide an improved machine of this class particularly designed for use in hotels, cafes, saloonsand other public places for vending paper or fibrous towels; a further object being to provide a machine of the class specified particularly designed for use in vending paper or fibrous towels from a roll of material mounted in a suitable casing and from which at each operation of the machine a predetermined length or strip of the material is fed from the roll and may be detached for use as a towel.'-

The invention is fully disclosed in the following specification, of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which 2- Figure 1 is a side view of my improved vending machine, Fig. 2 a front view thereof, Fig. 3 a sectional side view of the machine as shown in Fig. 1, Fig. 4 a sectional front View of the machine as shown in Fig. 2, Fig. 5 a sectional View approximately on the line 5-5 of Fig. 4,'Fig. 6 an approximate section on the line 66 of Fig. I, Fig. 7 a transverse section of two feed rollers which form a part of my improved machine, Fig. 8 a longitudinal sectional view of said rollers, and Fig. 9 a face view or side View of a strip of towel material after it is passed between the feed rollers.

In the practice of my invention, I provide a main casing a having a back a which, in the form of construction shown, is provided at the top and bottom thereof with projectand the hinged pedestals a, a and a fit in,

correspondence aperturesin the left hand side a of the casing a, and the pedestal a on the right hand side of the casing a also fits in the corresponding aperture in the right hand side a of the casing a all as clearly shown in Fig. 4, and the pedestals a and a in the right hand side portion of the casing a are inclosed by a supplemental casing or laterally directed extension a at the bottom of and on the right hand side of the main casing a.

In Fig. 6 I have shown the method of hinging the pedestals a, a, and a at the left hand side of the main casing a, the pedestal a being shown in Fig. 6, and said pedestals are hinged to the back a of the main casing a and are provided with slotted feet a through which are passed bolts a provided .with thumb nuts a, and this construction is shown in dotted lines in Fig. 2 and full lines in Fig, 3, and by means of this construction the pedestals a a and a at the left hand side of the casing a may be rigidly held in position for use as shown in Figs. 4 and 6, or may be turned outwardly as shown in dotted lines in Fig. 6.

The left hand side a of the main casing a, the right hand side a ,the top a, the bottom a, the front a and the supplemental casing or extension a at the right hand side of the main casing a are all formed integrally, and are rigidly connected with the back a of the main casing a by means of projecting ears 0," at the top a and bottom a which are rigidly secured to the projecting members a of the back a.

The back a, of the supplemental casing a Which is formed integrally with the back a of the main casing a is provided with apedestal a which fits in the corresponding recess in the outer side wall a of the supplemental. casing (1 as clearly shown in F ig. 4 and as partially shown in Fig. 3.

From this description, it will be seen, that the casingof my improved machine consists of a main part and a supplemental part, the back of both parts being the same and the sides, front, top and bottom of both parts being formed integrally and being detachably connected with the back part, but my invention is not limited to any particular means for connecting said parts of the casing of the machine, nor other features thereof as described.

.Mounted'in the top portion of the main part of the casing, and in the oppositely arranged pedestals (1 thereof is a roller'b on which is wound .a strip or sheet 6 of paper from which towels are formed as hereinafter described. Below the roller 1) are two main feed rollers c and d which also serve as cutters for perforating or partially dividing the strip 6 at regular intervals, and these rollers are also corrugated diagonally or otherwise as indicated. at o and d in Figs. 1 and 7 for the urpose of crimping, craping or otherwise orming the strip 6 into such shape or manner as to adapt it to serve more conveniently and readily for the purpose intended, or as towels.

The rollers c and (l are of predetermined dimensions and designed at each complete revolution to feed a predetermined length, say from fifteen to elghteen inches, of the strip 6 through the front of the maincasing at a at each complete revolution of said rollers, and said rollers are also provided one with a longitudinal row of suitably formed recesses 0 and the other with a longitudinal row of suitably formed teeth or projections d which, at each complete revolution of said rollers will form in the strip or sheet 6 a transverse'row of a ertures b as clearly shown in Fig. 9, sai apertures being separated by narrow longitudinal strips or connecting members b and at each complete-revolution of the rollers c and (Z in the operation of the machine as hereinafter described a part or section of the strip, or sheet b is fed forward throu h a transverse mouth or aperture a in the out a of the main casing a at a, and in this operation the transverse apertures b in the strip or sheet 6 are fed forward to a point 6 in Fig. 3, at which point the transverse mouth or aperture a is provided with downwardly directed transverse severing devices a which operate through or in connection with the transverse apertures b in the strip or sheet -6 and a quick upward pull on the projecting portion 1) of said strip or sheet will tear off said projecting portion which may be used as'a towel. The mouth or aperture a in the. front of the main casing a at a and at whichthe severing devices a are located is provided with'an inclosing projecting casing or guard from which the projecting portion 1) of the strip or sheet above referred to projects, and after said part b of the strip or sheet I) has been torn ofl", the said projecting casing or guard of the mouth or aperture a1. prevents the insertion of the fingers, or of a thumb and finger, or of an instrument in an eifort to take hold of the end of said strip or sheet I).

In the construction shown, the dia onally arranged corrugations c and d of t e rollers c and d produce corresponding diagonally arranged projections or teeth on the face of said rollers and corresponding depressions, and in the construction shown, these teeth or projections not only serve to crimp or crape or break the surface of the paper, strip or sheet 6 but also serve as inter-meshing gear teeth for the said rollers, and by means of which one of said rollers is turned by the other, in the operation of the machine as hereinafter described.

The object of hinging the pedestals a, a and a, on the left handside of the casing a as shownat a in Fig. 6 and as above de-' scribed, is to facilitate the mounting of or removal of the rollers b, c, and d; and the object of providing pedestal bearings for these rollers independent of the cover of the machine is to provide a construction whereby the machine may be opened up for inspection without disturbing any of 'the operating parts thereof.

The rollers c and d are secured to their shafts respectively by a key and key way construction well known and plainly shown in connection with the roller 0 at 0 in Fig. 6, and by means of this construction, in mounting the rollers upon the shafts, the key is first inserted in the key way of the roller and the roller and its key then passed over the shaft 0 as willbe understood, the

pedestal a being first moved outwardly as shown'in dotted lines in Fig. 6 to permit of this 0 eration. e-Rigidly secured to the shaft 0 of the roller 0 is a crank disk e, and lateral motion of this disk is prevented by the pedestal a, as plainly shown in Fig. 4; the disk e is provided with a wrist pin e rigidly secured thereto, and operating upon the wrist pin e is a spiral sprmg e rangln vertically there'- from and which is secure at its lower end to a post e rigidly secured to and extending forwardly from the back a of the machine as shown in Fig. 6 and indicated in Fig. 5. The wrist pin e is also rigidly connected to a ratchet disk e provided at its center with a bearing adapted to operate in connection with the end of a shaft c to be described later. The sprin e operates to normally hold the disk 6 an the ratchet disk e in the position shown in Fig. 5. The ratchet disk carries a spring pawl e' shown in Fig. 6.

, Operating in the pedestal a is a shaft e provided at its outer end with a crank e rigidly secured thereto, and inwardly of the pedestal a is a driving disk 6 also rigidly secured to theshaft e, and the shaft e extends through the driving disk e inwardly thereof and occupies the bearing of the ratchet disk 6 as plainly shown in Fig. 4.

As will be seen, the pedestal a supports the crank e and driving disk 6 and the disk construction 6 and ratchet disk '6 are supported by the pedestal a and the shaft e. Secured to the cover of the machine and extending rearwardly into the supplemental casingu is a vertically arranged -artition 6 plainly shown in Fig. 5 which follows approximately the contour of the ratchet disk 6 to Y the bottom portion thereof from which it extends horizontally to the back a 'of the machine, and as shown in F 4 this partition is bent away at its upper end from the right hand face of the ratchet diske and the partition e is provided with a segmental rib e t at right angles to the partition 6 and which also follows approximately the contour of the ratchet disk e extending from a point adjacent to the lower side of said ratchet disk forwardly and upwardly to any suitabledistance, or as in the shown, approximately onequarter of the circumference of the ratchet disk e. '5 V Pivoted at e to the partition 6 is a pawl 6 operating in connection with the teeth on the ratchet disk e and held normally thereon by a spring e also pivoted to thepartition 6 at e and this pawl prevents rc-tation of the ratchet disk 6 in a directionbpposite to the arrow 00 as shown in Fig. 5.

As shown in Fig. 4, the ratchet disk e and the driving disk 6 are so mounted as to have a space between their adjacent faces, and extending downwardly into this space and formed integrally with the cover of the machine is a finger e, the shape of which is shown in Fig. 3

The driving disk e is provided as shown in Fig. 6 with a tooth e" which operates in connection with the spring pawl 6 on the ratchet disk 6'' to prevent the independent rotation of the driving disk 6 in a direction opposite to the arrow 3 in Fig. 6 as will be understood, and the tooth e" is indicated in dotted lines in Fig. 5.

The ratchet disk. 6 andtthe driving diske are provided with coin recesses 6 and 6 respectively which are simllar 1n contour as shown in dotted lines in Fig. 4, and of the transverse shape shown in Fig. 6, and these recesses extend radially into their respective.

disks.

Mounted on the top portion of the supplemental casing a is coin chute a which communicates with a corresponding slot a? in the top portion of the supplemental casing an as shown in Figs. 4 and 5. .In the lower part of the supplemental casinga and between'f the side wall a thereof and.

the partition 6 is a drawer or coin receiver 6 1 and as plainly shown in Fig. 5 the drawer e is provided with a look 6 the tumbler of which operates in connection with the front wall or cover of the supplemental casing a by means of which the drawer 6 can be locked in position in the supplemental casing; and said drawer 0 preferably extends from the front part of the cover rearwardly to the base a shown in Fig. 5. i

According to the construction above described, it will be seen, that the spring 6 tends normally to hold the wrist pin e vertically under the shaft 6} and the recess 6 is so locatedithat its corresponding normal position is directly under the coin chute at.

The driving disk 6 is free to turn in the direction of the arrow 3/ in Fig. 6,by means of a crank 65, and the spring pawl e is free to work over the tooth e and when the pawl c and the tooth 0? are adjacent as shown in Fig. 5 at e the recess 0 in the driving disk 6 registers with the recess 6 and is also directly under the coin chute a, and the driving disk 6 is prevented from being turned in a direction opposite to the arrow 12 of Fig. 5 since the tooth a" will strike the spring pawl e tending to turn the ratchet disk 6 which is prevented from turning by the pawl 6 Therib e of the partition 6 as shown in Fig. 4 extends over and ccgvers the opening of the space between the driving disk 6 and the ratchet disk 6 The operation of this machine will be readily understood from the foregoing description when taken in connection with the accompanying drawings and the following being released drops downwardly therethrough and is received by; the recesses e and 6 the coin aresting'in the bottom thereof, its. shape conformingto the shape of the bottom of the recesses as shown in Fig- 42- j 7 0 The crank e is," as before stated, prevented from being turned to the left, but if it now he turned to the right the driving disk 6 will move or turn the ratchet disk e because of the coin engaging the edges of the recesses e fh'and, e as will be understood, and as the two disks are now turned together toward theright the 'spring .9 tends to resist the revolution of the ratchet diskre throughout a half revolution thereof as willbe 'understood, and when the driving disk 6 by 'means of the coin in the recesses e and c has turned the ratchet disk e more than i half a revolution the spring e will tend to assist in the rotation of the disk 6 and the spring pawl '0" will engage and press upon the tooth e and the twodisks will continue to rotate together.

When the coin in its revolution with the disks has reached a point shown in dotted lines at f, the lower end of the finger e engages the inner edge of the coin f, and on a further revolution of the two disks the coin is gradually pushed out by the edge of the finger e occupying in this operation the position f until at f the coin is entirely freed from the recesses e and e in the disks 6 ande, and drops downwardly by gravity over the peripheries of the disks 6 and e around under the rib e and into the drawer c. When the coin has left the recesses as above described, the driving disk 6 is free to move independently of the ratchet disk e and the spring 6 operates to pull the disk 6 to a completion of its revolution or toward its normal position, as shown in the drawings, and thereby causes the spring pawl e" to remain adjacent to the tooth e", and thus the disk e and the disk 6 continue to rotate together, and when the complete revolution has been effected the initlal conditions are restored and a further revolution of the disk c is impossible without the insertion of another coin.

As hereinbefore stated, the paper 6 on the roller 1) is fed between the two rollers c and d and, as just described, on the insertion of a coin into the machine, the roller 0 may be revolved through one revolution by means of the crank 6 and durin this operation a predetermined length 0% paper. is fed between the rollers 0 and d thus giving the treatment hereinbefore mentioned of crimping or craping its surface, which give ita porous absorbent texture.

The longitudinal rows of recesses c and corresponding teeth d are so located upon the rollers c and d that when the said rollers are in their normal positions, these recesses and teeth occupy; relatively the position shown in Fig. 7 so that on a completion of one revolution of the rollers above described, the predetermined length of paper towel is formed and fed out through the delivery slot at a =and is perforated or 'cut trans;

versely by the recesses c and projections d and this transverse row of perforations is fed forward to and stopped at the transverse edge a of the delivery aperture a so that the predetermined length of towel, or

strip 6 may be torn off along said edge. As will be understood in connection with the above description, the rib .6 and the partition e direct the path of the coin discharged by the finger e from the recesses e ande and prevent its falling off into the interior of the machine, and the point in the revolution of the disks 6 and e at which thecoin is ejected from the recesses and e by the finger e is determined by, and may be adjusted to occur at any desirable point in the revolution of the said disks by varying the contour of the finger and the length of the rib e as will be understood.

The crank 6 will normally hang, due to its weight, at the lowest point of its revolution as shown in Fig. 4, or it may be held in this position normally by any desired means, but it will be understood that if by accident it does not occupy this position when the coin is inserted, the drivin disk e may be revolved idly in the direction of the arrow of Fig. 6 until the recess c registers with the recess a and with the coin chute a when the coin will drop into the recesses e and 6 and the machine may be operated as above described.

When the roll of paper 6 on the roller 6 has become exhausted, a new one may be substituted by first removing the cover of the machine and then letting down the hinged pedestal a constructed as above described.

The method of connecting the cover to the base a ma be modified and arranged in any desire way and other details of the construction of my improved towel vending machine may be changed and modified without departing from the spirit of my invention or sacrificing its advantages, and I do not wish to be limited to the exact forms of construction and details by which the principle of my invention is applied as here- 1n set out.

Although. I have shown and described the feed rollers 0 and d as geared together by means of teeth or projections and corresponding recesses formed in the faces thereof, it will be apparent that these rollers may be geared together by means of gears at the ends thereof, or in any other desired manner, and by means of the construction herein described, I provide a machine which will form from a roll or smooth paper a towel having a rough, porous and absorbent surface or texture delivered for use upon the insertion of a coin in the machine and upon the turning of a crank to operate the same; but my invention is not limited to the construction, combination and arrangement of the various parts of the machine herein shown and described, since it will be evident that a roll of paper previously craped and made porous and absorbent and, previously provided with transverse rows of perforations or apertures may be used and fed out between differently formed rollers controlled by the coin operated mechanism described, or some other form of coin operated mechanism may be used to control the corrugated feed rollers and perforators constructed as described;

and various other changes in and modifica- This application is a division of a prior application filed by'me May 13, 1909, Ser. 495,801, and the invention described and claimed herein is limited to those features of the construction shown and described which are independent of the check or com controlled operating devices; the prior applica tion referred to being limited to the check or coin controlled operating devices and tea tures pertaining thereto.

Having fully described my invention what I claim as new, and desire to secure by Letters Patent is z 1 1. In a machine of the class described, a casing composed of a back member and ade-v 'tachable front provided with sides, one of said sides being provided with recesses and, the corresponding side of the back being provided with hinged pedestals adapted to fit in said recesses and to form supports for rollers placed in saideasing.

2. In a inaehlne of the class descrlbed, a

casing composed of a back member and a detachable frontprovided with sides, one of said sides being provided with recesses and the corresponding sideof the back being provided with hinged pedestals adapted to fit in said recesses and to form supports for rollers placed in said casing,'the other side being also provided with a recess and the 22nd day of September 1909.
